phenol formaldehyde powder production process

Bakelite is a polymer made up of the monomers phenol and formaldehyde. This phenol-formaldehyde resin is a thermosetting polymer. We cannot deny the presence of polymers in our lives. We are surrounded by objects, most of which, some way or the other have a polymer associated with them.

Influence of the Formaldehyde to Phenol Ratio in Resin

Influence of the Formaldehyde to Phenol Ratio in Resin

Mar 16, 2002 Phenol−formaldehyde resins synthesized using different formaldehyde-to-phenol molar ratios (F/P ratios) were used as precursors for production of activated carbons from steam activation and KOH etching. The base-catalyzed method was employed in the synthesis with the F/P ratio ranging within 1−4. It was found that the resin yield decreased with the F/P ratio, while the fixed …
